Underlay模型下基于优化遗传算法的认知无线电网络频谱分配
Spectrum allocation of cognitive radio network based on optimize genetic algorithm in underlay network
通过分析一种基于underlay频谱分配方案下的无线电网络物理连接方案，建立该频谱分配方案下的数学模型。并通过该数学模型的辅助，以最大化系统效益为准则实现，提出了改进的遗传算法的认知无线电网络频谱分配算法，该算法不仅能快速收敛，而且通过补充随机个体的方法避免陷入局部最优。并在文章最后通过实验证明其有效性。
By analyzing physical connection of cognitive radio network in underlay,a mathematical model of spectrum allocation is introduced here.Under the mathematical model,this paper give a optimize genetic algorithm for maximizing the profit of network.The algorithm not only is convergent,but can avoid the remaining local optima by adding the radom individuals.Finaly,the the proposed method was demonstrated by the experimental results in this paper.
